Question
A person rows 300 km against the current in 5 hours and
travels 540 km along the current in 6 hours. How much time will he take to row 660 km in still water?Solution
ATQ,
Upstream speed = 300 / 5 = 60 km/h
Downstream speed = 540 / 6 = 90 km/h
Speed in still water = (60 + 90) / 2 = 75 km/h
Required time = 660 / 75 = 8.8 hours
